In theory, using MicroPython on the ESP32 is easy — just flash an image ... help you and one we recently noticed was MPY-Jama. The IDE provides source code editing, of course.

If you’re not familiar with coding, you can use the WiFiScan example file in the Arduino IDE as a reference for this project.

Plus the Arduino needs to be plugged into the host computer via USB to function, a rather quaint idea to many in 2018. These were just some of the reasons he decided to port Grbl to the ESP32 board.

It can be programmed using the ESP-IDF framework or Arduino IDE, so it's accessible to both professionals and hobbyists.
